Brass coupling SANHA 4270G GW 28 mm x 3/4" (model 142702834)

SANHA 4270G GW 28 mm x 3/4" is a brass coupling designed to connect a 28 mm socket pipe to a 3/4" threaded fitting. The fitting provides a transition between metric socket-style pipes and imperial threaded components, suitable for plumbing and heating systems. Constructed from dezincification-resistant brass, the coupling delivers mechanical strength and corrosion resistance required for water and heating installations in residential and light commercial environments.

Advantages

The brass coupling offers a reliable mechanical connection between a 28 mm socket and a 3/4" thread without the need to modify existing threaded parts. Its material composition resists corrosion and dezincification, helping to maintain flow integrity and sealing performance over time. The compact design allows installation in confined spaces and is compatible with common pipe joining techniques used in plumbing and heating. The product is suitable for use with copper and many plastic piping systems when paired with the appropriate socket or insert.

Suitable for

• Connecting 28 mm metric socket pipes to 3/4" threaded valves and fixtures
• Residential hot and cold water supply lines
• Heating circuit connections and radiator installations
• Service lines in light commercial plumbing

Key specifications

• Material: dezincification-resistant brass
• Connection A: 28 mm socket for insertion-type pipe joining
• Connection B: external 3/4" thread
• Application: potable water and heating systems
• Design: compact coupling for transition between metric and imperial fittings

How to use

Prepare the 28 mm pipe according to the chosen socket joining method (clean, deburr and insert appropriate insert or sleeve if required for plastic pipes). Apply the recommended solder, press, or adhesive procedure for the socket side depending on the pipe material and joining standard. Screw the 3/4" threaded side into the mating component using appropriate sealing method for the thread type (e.g., thread sealant tape or paste) and tighten to the manufacturer-recommended torque to ensure a secure, leak-free connection. Verify alignment and test the assembly under working pressure before final commissioning.

Usage recommendations

Use compatible joining tools and inserts for the pipe material, follow local plumbing codes, and perform pressure testing after installation. Avoid exposing the fitting to aggressive chemicals or environments not intended for dezincification-resistant brass. When in doubt, consult installation guidelines from SANHA or a qualified installer to ensure correct application.
